Abstract

This paper presents a behavioral system based on artificial life paradigms. The system, called αCS. is suited to be employed for the animation of virtual entities immersed in concurrent and changing environments. The αCS system is the extension of an original classifier system to collaborative abilities. The main modifications enable αCS to use cooperation and communication to build dynamically the behavior of virtual entities which goal is to achieve several tasks. Our classifier system is evaluated by the way of two applications. Firstly, we present the performances of αCS in an optimization problem consisting on following a moving target. Secondly, we investigate a complex 3D world where autonomous entities and avatars interact. Through the simulation of a virtual game, we show how the integration of our system in virtual entities enables to build evolving behaviors thanks to adaptation, communication and auto-organization.
